CORPORATION OF NEW YORK.

WIRE-FEEDING DEVICE.

Application filed February 17, 1920, Serial No. 859,463. Renewed March'13, 1922. Serial No. 548,459.

To all whom it may concern: Be it known that I, J AMES L. ANDERSON,

a citizen of the United States, and resident;

of Bayonne, in the county of Hudson and State of New Jersey, haveinvented a new and useful Wire-Feeding Device, of which the following isa specification.

The object is to provide a simple, compact and effective wire-feedingmeans for welding torches. To this end the invention comprises theunitary supporting and feeding device, hereinafter described in itspreferred embodiment and more particularly pointed out' in the appendedclaims.

In the accompanying drawings, forming a part hereof:

Fig. 1 is a side elevation of the invention an adjusting bracket;

Fig. 2 is an enlarged plan view of the d e; vice, omitting the motor;Fig. 3 is a front view of the device;-and

Fig. 4 is a detail perspective view of a part on a still larger scale.

The drawing represents an oxyacetylene or like welding torch 1, which ismounted upon an adjusting bracket 2, forming the subject-matter of aseparateflapplication. The torch has a cylindrical stock 3 and a tip 4containing passages 4* from the flame jets are delivered. A

On the upper part of the torch stock, above the bracket, is a c1amp-5for supporting the wire-feeding means. The clamp comprises two parts,each comprising a portion of two laterally united collars 6, 7 and aconnecting web 8. The collar 6 is relatively small, to embrace the torchstock, and the collar 7, relatively large to receive a cylindricalelectric motor 9. The two pieces of the clamp are united by screws 10passing through the webs 8, the relations being such that when thecollars are thus assembled their ends 11 are separated, so that they maybe drawn together resiliently by screws 12 upon the stock and motor.

The motor may thus be supported at the front and somewhat to one side ofthe stock of the torch, with its armature shaft 14 projectingdownwardly. The motor is pro-' which the motor-clamping portion of theother half. A- supplementary bracket piece 18 is applied to the innerface of a hub 19 on the lower end of the bracket 16, said piece having atransverse opening and a projecting bushing 20, which latter passesthrough the ,hub and is engaged at the outer side there- The bracketpiece 18 also has another transverse opening 2O in. which, by nut- 27,'fissecured the stub journal of a grooved applied to a torch, which ismounted upon guide roller 28', peripherally opposite the feed roller 23.Lugs 29, 30 .projectin'g inwith the interval between the rollers. Sec

section extending downward to the torch tip 4,'where its lower end issecured at the entrance of a wire duct 33 passing through the tip. .Thewire a from a suitable supply, notv shown; passes through the guide tubeand between the rollers, downward to and through the torch tip, whereits extremity is continually melted off by the heat of the jets to additself to the metal of the weld. The construction of the tip with itspassages for jets and for the'wire, and the combination of the same withmeans, generally, for

'feedin wire through the wire passage, form the su ject for a separateapplication.

What I claim as new is: 1. A wire-feed for welding torches comprising aclamp including a torch-embracing portion, shaft bearings and amotor-carrying portion, a transverse shaft in said bearings, a wire-feedroller and a gear-wheel on said shaft, and a motor supported by themotor-carryin portion of the clamp, geared to said gearheel.

2. A wire-feed for welding torches, in cluding a clamp comprisingtorch-clamping and motor-clamping collar portions laterally united witheach other, a motor in the motor-clamping portion,and a transverse shaftin the support geared to the motor shaft and bearing a wire-feed roller.

,tions of a guide tube -32"are secured at their adjacent ends in theseopenings, the lower 3. A wire-feed for welding torches, in-

cluding a clamp comprising torch-clamping and motor-elamping collarportions laterally united with each other, a motor in the motor-clampingportion having its shaft projecting downwardly, brackets extendingdownward from the clamp, and a transverse shaft journaled in saidbrackets bearing a feed roller and geared to the shaft of the motor.

4. A Wire-feed for Welding torches, comprising a clamp having atorchembracing, portion and a motor-carrying portion. a motor supportedby said motor-carrying portion of the clamp, a bracket on the clampbearing a guide-roller. a shaft journaled in the bracket bearing afeed-roller opposite the guide-roller, and gearing between said shaftand the motor.

5. In a wire-feed for welding torches, the

combination of a torch clamp, a wire-feed roller carried by the clamp, amotor on the clamp geared to said feed-roller, a bracket piece held fastto the clamp on a pivot per- Initting its angular adjustment about theaxis of the feed roller, and a guide roller carried by said bracketpiece peripherally opposite the feed roller.

6. In a Wire-feed for Welding torches, the combination of a torch clamp,a Wire-feed roller carried by the clamp, a motor on the clamp geared tothe feed roller, and a bracket piece held fast to the clamp on a pivotpermitting its angular adjustment about the axis of the feed roller andcarrying a guide roller opposite the feed roller and means for guidingthe Wire in alinement with the interval between the rollers.
